Abstract (en)

[origin: EP0605108A2] A process for forming images which comprises (a) generating an electrostatic latent image; (b) contacting the latent image with a developer comprising a colorant and a substantial amount of a vehicle with a melting point of at least about 25 DEG C, said developer having a melting point of at least about 25 DEG C, said contact occurring while the developer is maintained at a temperature at or above its melting point, said developer having a viscosity of no more than about 500 centipoise and a resistivity of no less than about 10<8> ohm-cm at the temperature maintained while the developer is in contact with the latent image; and (c) cooling the developed image to a temperature below its melting point subsequent to development. Specific processes disclosed include electrophoretic development processes, polarizable liquid development processes, and photoelectrophoretic development processes. Optionally, the developed image is transferred to a substrate subsequent to development.
